INTRODUCTION
2011KCI and 2211KCI are input cards specially
designed for Konecranes. They can be placed in
any of Nokeval E and F series large displays, like
1000F4.
The card provides one (2011KCI) or two (2211KCI)
2-8 V analog input channels. The upper end of
these can be scaled freely, and independently on
each channel.
These models have been superceded by 2012KCI
in spring 2007.
A separate Technical manual is available on
request, covering more details of the KCI displays.

ORDERING
Ordering
Obsolete
It is recommended to replace the 2011KCI and
2211KCI by more advanced 2012KCI, which has
been available since spring 2007.
Order code
Example: 1000F4 – 2011KCI – 230VAC
The order code consists of several parts. The first
part describes the large display type, the next part
defines the input card type, and the last part
selects the supply voltage.
Large display type
Nokeval has four cases for large field displays.
These are:
575 Five 57 mm digits, plastic enclosure
1000 Three to four 100 mm digits, steel
1100 Five to six 100 mm digits, steel
1800 Three to five 180 mm digits, steel
The letter after the case size is either E or F. This
tells the type of the internal electronics. They are
principally the same but have different looks. The
main difference is that the input card is upside
down in the E chassis. Since beginning of year
2003 all displays have been with F chassis.
The number after the letter defines the number of
display digits.
Input card type
These large displays use Nokeval 2000 series
input cards. Custom input cards 2011KCI and
2211KCI have been designed for KCI.
Power supply options
Before summer 2009, the large field displays have
been available with three power supply options:
Name Voltages
-24VDC 24 VDC
-48VAC 48 VDC or VAC
-230VAC 115 or 230 VDC or VAC
After summer 2009, the input voltage range of the
230 VAC model has been extended to cover the
range 41...265 VDC/AC, removing the need for a
separate 48 VAC model. The voltage options are:
Name Voltages
-24VDC 24 VDC
-48/230VAC 48, 115, or 230 VDC or VAC
Common models
1000F4-2011KCI-48/230VAC: four 100mm digits,
1 input, power 48 to 230 VAC.
1000F4-2211KCI-48/230VAC: four digits, 2 inputs,
power 48 to 230 VAC.

INSTALLING
Mounting
Dimensions for 1000F, 1100F, and 1800F:
Opening the case
To access the electrical connections and the small user interface used for configuring the unit, the steel case
has to be opened. First unscrew all the screws surrounding the display, then lift off the black steel frame and
the red plexiglass. Finally unscrew the screw that is located on the right hand side of the rightmost digit. Now
the display assembly may be turned away on its hinges.
Inside the main case
The electronics unit
The electronics unit may be opened or detached from the case. To open it, unscrew the four M3 screws that
are holding the cover on its corners. If the unit has to be detached, unscrew the other screws on its top and
bottom sides. Normally there is no need to open the electronics unit. Caution! Opening the electronics
unit exposes parts carrying lethal voltages on units powered with more than 24 V supply!

Supply voltage and earthing
24VDC models
Bring the supply voltage to the connector indicated in the picture. If the supply voltage is more than 24 V, the
enclosure must be reliably earthed using the M4 screw provided. A pre-fuse is not necessary, but if one is
used, it should be at least 2 AT.
48/230VAC models
Bring the Live and Neutral wires to the electronics unit as in picture. A pre-fuse is not necessary, but if one is
used, it should be at least 1 AT.
Connect the Protective Earth wire to the M4 screw using the Faston connector provided - a Faston crimping
tool is needed.
For electrical safety, the power and signal wires must be fastened using cable ties or equivalent so that if one
signal wire is detached, it can not touch any of the power supply wires, or vice versa.

Configuring
The display unit may be configured either on the
small display and buttons inside the main case, or
with a programming cable.
Inside buttons
Open the main case as explained above. Use the
small display and four buttons to configure the
display unit. Using the buttons is explained in
chapter User interface.
Via a programming cable
Using the programming cable is possible only on
models equipped with circuit board ”2012” in slot A.
The programming cable is attaced to a pin header
marked "POL" on the input card in slot A. To
access it, both the main case and the electronics
unit cover have to be opened. Removing the
electronics unit cover exposes parts carrying
lethal voltages on units with supply voltage
more than 24 volts!
Nokeval provides two alternative programming
cables: "POL-RS232" for RS-232 port, and
"DCS772" for USB port.
In addition, an adapter for the pin header, called
"POL-3PIN", is required.
A free software MekuWin is used, available for
Microsoft Windows. Select SCL protocol, 9600
baud, and address 0 or 126.
For the configuration menu contents, refer to the
chapter User interface.

OPERATION
2011KCI
Input processing
The input is measured using an analog-to-digital
converter. The reading is scaled to a weighing
reading using the Lo and Hi setting in the
configuration menu. When the input signal is 2.00
V, the display will indicate the Lo value, which is
almost always set to 0. At 8.00 V input, the display
will indicate the Hi value. The measurement unit
can be freely selected (kg, ton, lbs...), and there is
no need for the display unit to know it.
How many digits are displayed after the decimal
point, is defined with the Dec setting in the
configuration menu. The Dec setting can also be
used to show fixed zeros, which is useful when
displaying large readings (e.g. 10000 kg) and the
last digits would otherwise be nervous.
The display can be slowed down with a digital 3rd
degree lowpass filter.
The Dead setting can be used to round small
readings to zero, or to prevent negative readings
Flt switch
The input card 2012KCI has one digital input.
Closing a switch connected to it will make the
display to show "Flt" (except in Remote state).

Each 2 to 8 V input signal is scaled to weighing
reading using the Lo, Hi 1, and Hi 2 settings in the
configuration menu. Lo is almost always 0, and Hi
1 and Hi 2 correspond to the full scale weighs of
the input channels. The unit of the scaling can be
freely selected (kg, ton, lbs...) and there is no need
for the display to know it. Then, negative readings
are prevented (limited to 0), before summing up
the readings. A tare value is subtracted. A new tare
value can be stored using an external switch.
The 3rd order lowpass filter can be used to
attenuate fluctuations and disturbances. The filter
is bypassed a couple of seconds after power-up.

USER INTERFACE
This chapter describes how to use the small
display and buttons inside the display unit to
perform configuration. The contents of the
configuration menu is described here too.
The small display inside the case and the large
display always show the same contents, except
that the large display may have less than 6 digits
and then it shows dashes if the content does not
fit.
The displays may be in the following states:
•Normal state – displaying the readings.
•Configuration state – changing the settings.
Normal state
After power-up, the unit is in the normal state,
displaying the input readings according to the
configuration.
The A3 indicator LED is lit when the external switch
controlling the FLT or Tare function is active.
The tare function can be used also by pressing the
* key, and the tare value can be reset by pressing
* and > together (2211KCI only).
Configuration state
Entering
Press the * and ^ keys simultaneously two
seconds in the normal state to enter the
configuration state. When entered, the Conf led will
light.
Navigating
Use the ^v keys to browse the menu. To see a
configuration value and possibly edit it, push the >
key. Return to the menu with the * key.
Editing
Integer values, such as the Dec setting, are
adjusted with the ^v keys.
Floating point values, such as scaling and the
lopass filter, are edited with ^v> keys: select digit
to edit (blinking) with > and change it with ^v.
When the decimal point is blinking, it can be
moved with ^v. The first digit can be replaced with
a minus sign.
Exiting
When all settings are done, exit from the
configuration menu with * key. Two options are
shown: Save to keep the settings made, and Undo,
to discard all changes. Select ^v Save or Undo
and push >. (Or push * to get back to the menu.)
2011KCI configuration menu
Dec Number of digits after the decimal point. E.g. with value of 1, the reading is displayed with one
digit after the decimal point.
If the dec setting is negative, the corresponding number of last digits is rounded to zero.
Example: Dec= -2, the display will step 0, 100, 200...
Lo Displayed reading at the minimum input signal (2 V). Almost always 0.
Hi Displayed reading at the maximum input signal (8 V).
Lopass Damping, will slow down display fluctuations. Set the time constant (63% of the final change) in
seconds. Fast operation = 0.
9
Dead Dead zone around zero.
Dead>0: Display readings smaller than Dead are rounded to zero.
Dead=0: Negative readings are prevented.
Dead<0: Both positive and negative readings are displayed.
2211KCI configuration menu
Dec Number of digits after the decimal point. E.g. with value of 1, the reading is displayed with one
digit after the decimal point.

Example: Dec= -2, the display will step 0, 100, 200...
Lo Offset that is added to the display reading. May be negative. Almost always 0.
Hi 1 Displayed reading at the maximum input signal on channel 1.
Hi 2 Displayed reading at the maximum input signal on channel 2. When there is a signal on both
channels, the sum is displayed.
Lopass Damping, will slow down display fluctuations. Set the time constant (63% of the final change) in
seconds. Fast operation = 0.
Dead Dead zone around zero.
Dead>0: Display readings smaller than Dead are rounded to zero.
Dead=0: Negative readings are prevented.
Dead<0: Both positive and negative readings are displayed.
Tare Tare value that is subtracted from every reading. Mainly for viewing, but can be edited too.
